| 1. | As the cells differentiate from spermatogonium to spermatids , the number and size of cb gradually reduce and shrink
随着细胞分化，拟染色质小体逐渐减少直至消失，推测拟染色质小体主要成分为核糖体。
|
| 2. | 1 . with testicular development , the products of c - myc translocate from the cytoplasm of spermatogonia to nuclei of spermatogonia
随着精子发育时期的不同， cngc产物在山溪蜕精巢中有从生殖细胞的胞质向胞核中转移的趋势。
|
| 3. | During the stages of primary and secondary spermatogonium , components of the nucleolus , called chromatoid bodies ( cb ) , are excluded from the nucleus
精原细胞阶段，部分核仁物质外排，成为拟染色质小体，其上聚集一群线粒体，构成“线粒体区” 。
|
| 4. | There was expression of cdc2 in nuclear and plasma of spermatogonia , primal spermatocyte , sperm cell , cdc2 also exists in sperm but is fewer than other cells
Cdcz在精原细胞、初级精母细胞及精子细胞中的胞浆与胞核中均有表达，精子中也有所表达，但相对淡染
|
| 5. | The results reveal that there are two types of spermatogonium , primary spermatogonia ( sg1 ) and secondary spermatogonia ( sg2 ) , in the early developmental stage of testes
生精细胞之间存在着间桥连接。大眼鳜具有初级精原细胞、次级精原细胞两种类型精原细胞。
|
| 6. | The males incubation at 26 , cortices of their testes degenerate into a thin albuginea . medulla are formed by testicular cords in which scatter spermatogonium
26下孵化的小龟精巢皮质退化成为一层薄的白膜，髓质有许多睾丸管构成，管腔内有散落排列的精原细胞。
|
| 7. | A variety of biology events occur during spermatogenesis , such as self - renewal of spermatogonia , meiotic division of spermatocyte and the spermiogenesis of spermatid
生精过程中发生了许多生物学的变化，如精原细胞的自我更新，精母细胞的减数分裂和精子细胞的变形。
|
| 8. | P and pr have relationships with spermatogensis and sperm maturation . 6 . the product of c - fos translocates from the cytoplasm of spermatogonia to nuclei of spermatogonia , then it induces the transcription of dna and regulate spermatogonial proliferation and spermatogenesis
C fos产物从精原细胞胞质中转移到胞核中后通过启动dna的转录而调控精原细胞的增殖，从而促进精子发生的进程。
|
| 9. | According to the changes of the structure of chromatin and the morphology of cell , the process of the typical spermatogenesis of cipangopaludina chinensis can be divided into five stages : spermatogonium , primary spermatocyte , secondary spermatocyte , spermatid and mature sperm
中国圆田螺典型精子发生时，根据染色质和细胞形态的变化，可将其发生分为以下五个时期：精原细胞、初级精母细胞、次级精母细胞、精细胞和成熟精子。
|
| 10. | Portunus , trituberculatus the spermatogonium exist in two different forms , the second form comes from the first one . during spermatogenesis , chromatins condense at different level . the nucleus changes into homogeneous since middle spermatid stage , and the nucleus extends into the radial arm
三疣梭子蟹在生精细胞阶段，染色质不同程度的浓缩凝集；在精细胞阶段，核质呈均质状，形成薄壁的圆球形核杯，部分核质延伸入辐射臂内。
